Unity android ndk及Gradle

使用联通网络上网，无法直接通过Unity Hub下载Android SDK和NDK

只能通过FQ，再手动下载

下载地址：

https://developer.android.google.cn/ndk/downloads/

下载时，需要匹配版本

https://github.com/android/ndk/wiki/Unsupported-Downloads

Unity 2021.3.11提示需要 NDK r21d

 Unity 2020.3.4 提示需要 NDK r19

  

配置后，虽然还是会提示警告，不是建议的版本，但至少是可以编译的了
